SPECIFICATION forming part of Letters Patent No. 662,061, dated November20, 1900.

Application filed December 28, 1899. Serial No. 741,839. (No model.)

To all whom, it ntcty concern:

Be it known that I, PETER DUCHSOHER, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Mechanical Movements, ofwhich the following is a specification.

The present invention relates to that class of organisms used in thetransmission of power in which the force is multiplied in transmission;and the objectof the invention is to provide an improved organism ofthis class, one especially adapted for the utilization of manual powerin the production of heavy strains. The invention relates solely to thetransmitting mechanism and has nothing whatever to do with the characterof the machine in which the power is utilized further than that itcontemplates the presence of such accessories as will make the improvedmechanism available for the production of some useful result. I maymention, however, that the invention is especially adapted for use inpresses of various kinds, lifting-jacks, windlasses, and many othermachines intended for producing heavy strains.

The primary element of the improved organism or the element to which thepower is applied primarily is a lever, and the ultimate element of saidorganism is a revoluble part, such as a wheel, a drum, a shaft, a disk,or the like. An incident of the operation of the device is'that theoscillating or reciprocating motion ofitheilever is during itstransmission converted into rotary motion; but if the final applicationof the power does not require rotary motion the motion may be againconverted by any of the well-known appliances for this purpose.

tional elevation thereof. Fig. 3 is a plan view thereof. Fig. 4 is aplan view thereof with some of the parts reversed and with the primarylever of the system omitted. is a section thereof on the line'5 5, Fig.2, looking in the direction of the arrow.

A represents the primary element, to which the power to be transmittedis applied. Pref-' erably it takes the form of a short lever capable ofbeing oscillated about a suitable fulcrum B, sustained by a suitablebase 0. The outer or receiving arm of this lever may be of any desiredlength, and to thisend it is preferably provided with a socket a orother appropriate feature for the reception of an extension A.

D is the ultimate element of the organism, or, in other words, theelement to which the power is to be transmitted. As before stated, itmay consist of any revolulole part; but for the purposes of thisapplication I have shown it as consisting of a drum suitably mounted soas to be capable of being revolved- To this end it is provided with aportion 61 in the nature of a journal, which occupies a suitable bearingin the base C, and with a flange d, that is engaged by overhangingbrackets E, that are secured to the base, the arrangement being suchthat the drum is capable of Fig. 0'

free rotary movement, but incapable of endwise movement relatively tothe base.

F is a ring or collar arranged with its axis coincident with the axis ofthe drum D and mounted so as to be capable of rotating in-' dependentlyof the drum. Preferably it is mounted upon the drum and is sustained bythe shoulder resulting from the flange d.

G is a lever fulcrumed to the ring-F at H. The inner end of this leveris shaped to form a cam I, which is adapted to engage the drum D whenthe lever is moved about its fulcrum in one direction and to bedisengaged therefrom when the lever is moved about its fulcrum in theopposite direction. In practice the actual movement of the lever aboutits fulcrum is very slight. A very slight moveto move in this direction.

movement of it in the opposite direction disengages the cam from thedrum and brings the lever into engagement with a stop J, carried by thering F, and thereafter the ring will partake of the backward movement ofthe lever. It will be observed that repetitions of these movements ofthe lever will cause the dru m D to be rotated in the direction of thearrow applied to it in Fig. 3 of the drawings.

The outer end of the lever G has pivotal engagement with the lever A,and to this end the outer end of the lever G may be bifurcated and thelever A provided with a stud K, which occupies the groove or openingbetween the two branches of the bifurcated end of the lever G, so thatby oscillating the lever A about its fulcrum B the lever G is moved.

The patent above referred to shows an organism comprising a revolublepart which is the equivalent of the part D herein shown and described, aprimary lever which is the equivalent of the lever A herein shown anddescribed, and means for transmitting movement from the short arm of theprimary lever to the revoluble part, so that in what I have so fardescribed the invention resides in the novel features for transmittingthe movement from the shorter arm of the lever A to the drum D.

The mechanism thus far describe is such that the movement of the lever Ain one direction only is transmitted to the drum D, its movement in theopposite direction being used in the recovery of the clutching andtransmitting mechanism. In order to transmit the movement of the lever Ain both directions to the drum, and thereby impart to the latter apractically continuous rotary motion, the parts lettered F to K,inclusive, are duplicated, similar duplicated parts being in.-

, dicated by similar letters of reference, with the prime-mark added tothe parts that have not thus far been described in detail. Theconstruction and mode of operation, of the parts F to K, inclusive, areprecisely the same as the construction and mode of operation of theparts F to K, inclusive,with the exception that the levers G and G areconnected with the lever A upon opposite sides of its fulcrum B, so thatsaid levers G and G always move in opposite directions. the completeorganism thus constructed every movement of the primary lever A istransmitted to the drum D, and the dilferentials of lof two leversadapted to be brought to the same radial position with respect to theaxis the several levers are such that the force is greatlymultiplied inits transmission. My invention relates to the organism thus describedand not to the means for applying the movement of the drum D. This meansmay, however, consists of a screw L, which is carried by the drum andmay work through a fixed nut in the upper cross-head of the press, thematerial to be pressed being in this case disposed between the base 0and the platen or bed-plate. When theresistance to the rotation of thedrum D is only slight and the i into a socketgin the lever G.

drum must be rotated a considerable number of times in order to bringthe parts topositions in which the resistance to the rotation of thedrum is materially increased, the lever A may be disconnected from thelevers G G i and the power for rotating the drum applied directly to oneor the other of said levers G G. In this connection the lever itself maybe seized or an extension, such as A, may be applied to it either byinserting the extension in the bifurcated end of the lever G or Thismanner of manipulating the device is shown in Fig. 4.. This figure alsoshows the lever G inverted and reversed, so that it will rotate the drumin the direction opposite the arrow in Fig. 3. This reversibilityof thelevers G and G is necessary in order to turn the drum in the reversedirection for the purpose of retracting the screw L or otherwiseremoving or releasing the pressure produced by the operation of thedevice.

It will be observed that by connecting the levers G and G to the lever Aupon opposite sides of its fulcrum one of said levers G G is necessarilylonger than the-other. This being so, if the studs K and K are placed atthe same distance from the center of oscillation of a lever A theshorter lever will move through a greater are than the longer lever. Inorder to avoid this and make the resistance to the movement of the leverA equal in both directions, the shorter one of the two levers G G isconnected to the lever A at a point somewhat nearer the center ofoscillation of said leverA than is the longer one of said levers G G.

It will be observed that, as shown in the drawings, that portion of thedrum D which is engaged by the lever G is of somewhat greater diameterthan the portion that is engaged by the lever G; This is for the solepurpose of providing a shoulder for the ring F to rest upon and does notin any way affect the operation of the device, because when the cams ofthe levers G G are in engagement with the drum said levers no longerhave the characteristics of levers, but become in their nature 1 andoperation rigid arms projecting from the drum and moving about a centerwhich is j the geometrical axis of the drum.

With

claim as new therein, and desire to secure by 5 Letters Patent, is
